What to make in Excel?

[sm321]

I like Excel, and feel like making some sort of 'program' in it. Any ideas of what to do? Thanks

I like excel to, but what do you mean with program?
last usefull thing I made was an BXP weekend calc for runescape
showed the exp gained every 30mins, total exp, and exp at the end
all calculated by entering your xp/h only.

Anything like you did, doesn't have to be for RuneScape, just like a special calculator or something?
